Krav Maga (Hebrew: קרב מגע‎, lit. “contact combat” or “close combat”) is an eclectic hand-to-hand combat system developed in Israel which involves wrestling, grappling and striking techniques, mostly known for its extremely efficient and brutal counter-attacks, as it is also taught to elite special forces around the world. It was derived from street-fighting skills developed by Imi Lichtenfeld, who made use of his training as a boxer and wrestler, as a means of defending the Jewish quarter during a period of anti-Semitic activity in Bratislava in the mid- to late 1930s. In the late 1940s, following his immigration to Israel, he began to provide hand-to-hand combat training to what was to become the IDF, developing the techniques that became known as Krav Maga. It has since been refined for both civilian and military applications.

Some refinements include, but are not limited to, the incorporation of elements from traditional Asian martial arts.

Krav Maga has a philosophy emphasizing threat neutralization, simultaneous defensive and offensive maneuvers, and aggression.Krav Maga is used by the IDF Special Forces units and several closely related variations have been developed and adopted by law enforcement and intelligence organizations, Mossad, Shin Bet, FBI, SWAT units of the NYPD and United States special operations forces. There are several organizations teaching variations of Krav Maga internationally.
